MACHINE FOR COATING PAPER.

SPECIFICATION forming part of Letters Patent No. 758,169, dated April 26, 1904.

, Application filed May 16,1903. strains 157,440. (No model.)

To all whom, it may concern:

Be it known that I, MARTI'N CASHIN, a citizen I of the United States, residing at East Pepperell, in the county of Middlesex and State of Massachusetts, have invented a new and useful Machine for Coating Paper, of which th following is a specification.

This invention is an improved construction of paper-coating machine, the object beingto provide a machine which will apply color to both sides of the paper at the same operation and one which will effectively and-evenly apply the color and work the same in thoroughly,

thereby avoiding any streaky appearance of the paper after being coated.

Another object of the invention is to provide a machine by means of which different colors can be applied to the opposite faces of.

the paper, if so desired.

With these objects in view the consists, essentially, in providing a frame comprising a vertical and a horizontal portion,

the vertical portion carrying drums over which paper passes and brushes for applying the color thereto, said brushes rotatingin adirection opposite the movement of the paper, the horizontal portion of the frame carrying a series of transversely-reciprocating brushes adapted to operate simultaneously upon opposite sides of the paper in directions transverse to the movement of the paper.

The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter, and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a side elevation of a ma- I chine constructed 1n accordance with myrnmodification residing mainly in the gearing invention 7 devices for operating the brushes and drums; and "Fig. 7 is a detail view.. In carrying out my invention I employ a 'inain frame A, comprising a vertical portion A and a horizontal portion A This main frame A may be constructed of Wood or metal, as preferred, and thefgeneral arrange: ment of thebeams and cross-pieces is toavery large extent immaterial. A paper-roll B is journaled upon the vertical portion A, the stripof paper passing under an idler C, carried by the frame, and over a drum D, journaled at the upper end of the vertical portion of the frame. The paper then passes under another drum D and then passes out centrally through the horizontal portion of the main frame to the drying rackor frame. (Not shown.) As the paper passes over the drum D color is applied to one face thereof by means of a rotary brush E, and as the paper passes under the drum D color is applied to the opposite face by means of a rotary brush E, said rotary brushes 'E and E receiving the color from feed-rollers E and E respectively, which are journaled in the fountains I 11* and E respectively. In this manner color is applied to both faces of the paper as it passes through the machine, and it is obvious that different colors can be applied to the opposing faces. An adjustable reciprocating brush Fis arranged at the top of the vertical portion of the frame and is adapted to spread the color evenly upon the paper while passing over the drum D, and an adjustable reciprocating brush F is arranged beneath the drum D and serves to evenly spread the color upon the opposite face of the paper while passing under the drum D, and for the purpose of thoroughly spreading and working in the color upon both sidesI employ a series of transversely-reciprocating brushes G; which are arranged in the horizontal portion of the main frame above and below the paper, said brushes being adjustable, as hereinafter described. It willthus be seen that I provide for applying the color to both faces of the paper and work the said color thoroughly, thereby avoiding any streaky appearance to the coated paper tions.

I shall now describe the means for rotating the drums and rotary brushes, together with the means for operating the reciprocating brushes, said means being those which I consider best adapted for the purpose intended; but it will be understood that these means may be varied or changed without departing from the broad principle of my invention.

A main drive-shaft H is journaled horizontally in the vertical portions of the main frame and receives its power in any suitable manner. A gear-wheel H is mounted adjacent the end of the shaft H and is adapted to mesh with a gear I, mounted upon the end of the shaft I, and the gear I also meshes with a gear K, mounted upon the end of the shaft carrying the drum D, and by means of which said drum is rotated, said gear meshing with a gear L, mounted on the side of the frame, which in turn meshes with a gear -M, mounted upon one end of the shaft carrying the brush E.- Thegear H also meshes with a gear K, mounted upon the end of the shaft carrying the drum D, and by means of which the said drum is rotated, and this gear K also meshes with the gear L, which in turn meshes with a gear M, mounted upon the end of the shaft carrying the brush E, and by means of which said brush is rotated,

the gears L and L being employed to rotate thebrushes in a direction opposite the movement of the paper. The shaft H also carries a beveled gear N, which meshes with a beveled gear N, mounted. upon the upper end of a shaft 0, journaledin brackets O and carrying a beveled gear P, which meshes with a beveled gear P, mounted upon the end of a shaft Q, journaled in brackets Q, saidshaft Q operating a parallel horizontal shaft Q by means of a belt Q and pulleys Q. The shafts Y Q and Q have the eccentrics R and R mounted thereon, to which straps S and S, respectively, are connected, said straps having pitmen S and S connected thereto, which pitmen are in turn pivotally connected to the reciprocating brushes G, and the eccentrics R and R are arranged in vertical alinement upon the shafts Q and Q and they are also arranged in such a manner that while the brushes connected with the eccentrics move in unison above and below the paper each alternate pair of brushes move in opposite direc- Eaeh brush G comprises the fibers G, the head G and a box G in which the head is adjustable by means of the ad justing-serews G. Each box G has guiding-ribs G upon the opposite sides, which travel in the grooved guides Gr, extending transversely across the horizontal portion of the main frame both above and below the paper. -The feeding of the color to the paper is regulated through the medium of the upper cone-pulleys T and the lower cone-pulleys U, together with the belts T and U, respectively, the upper pul- 6 5 leys being driven by means of a belt T, which extends around a pulley carried by the drumshaft and over a pulley mounted upon the end of one of the cone-pulley shafts, the opposite cone-pulley shaft having a pulley T over which travels a cross-belt Ti driving the pulley T, mounted upon the end of the shaft carrying the feed-roller E The lower conepulleys receive their power from the lower drum'shaft and transmit it to the lower feedrolls E belts U and U together with the necessary pulleys, being employed for this purpose. The feed-rolls E and E are adjustable vertically by means of screws V, and the rotarybrush E is adjustable horizontally by means of the screws V. In the construction shown in Fig. 6 I employ two additional gears W and W, which are interposed between the gears K and L and K and L.

By means of amaehine'constructed as herein shown and described I am enabled to effectively carry out all of the objects hereinbefore referred to, and the operation of the machine is as follows: The paper carried upon the paper-roll is passed under the idler C, over and around the drum D, under the drum D, and out between the reciprocating brushes, where it is carried in any suitable manner to a drying rack or frame, and powerbein g transmitted to the shaft H the drums D and D will be rotated, and the gearing connected with the main drive-shaft will cause the brushes E and E to first take the color from the feeding-brushes E and E rotating in their respective fountains, and these rotary brushes E and E will then apply the color to the opposite faces of the paper strip, said brushes rotating in a direction opposite to the movement of the paper. The stationary brushes F and F serve to spread the color upon the paper as the said paper passes over the drum D and under the drum D. These brushes F and F are adjustable by means of the regulating-screws, so that anydesired pressure can be had upon the said brushes. After the coloring-matter has been applied to'both faces of the paper in the manner described the paper is carried out in a horizontal direction between the series of horizontally-moiprocating brushes Gr, there being six brushes, three above the paper and three below the paper, said brushes being arranged in pairs, as shown, and these brushes are operated by means of eccentrics arranged upon the shafts Q and Q the shaft Q receiving its motion from a verticalshaft O, which carries a beveled gear at its upper end which meshes with a beveled gear carried by the main shaft H, and also another beveled gear which transmits motion to the shaft Q by meshing with the beveled gear carried by the of the paper, and as each alternate pair of brushes operates in opposite direction the paper will not be pulled to one side or the other in its passage through the machine. The amountof color is regulated by means of the upper and lower set of cone-pulleys, which receive their power from the upper and lower drums and transmit it to the upper and lower feed-rolls, so that by increasing or decreasing the speed of the feed-rolls the amount of color supplied to the, rotary brushes can be correspondingly increased or decreased.

It may be said that the transversely-reciprocating brushes F and F are operated by eccentrics F carried by the shaft 0, and their construction and arrangement are exactly like those of the brushes G.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine for coating paper the combination with the main frame comprising the vertical and horizontal portions, the rotary drums arranged in the vertical portion, ro-' tary brushes arranged adjacent the rotary drums, means for feeding the said rotary brushes, and the horizontally-reciprocating brushes arranged in the horizontal portion of the main frame, together with means for rotating the drums and rotary brushes, and means for reciprocating the horizontal brushes, as set forth.
